API NITRITE TEST KIT 180-Test Freshwater and Saltwater Aquarium Test Kit

This API Nitrite test kit is for testing fresh water or salt water for levels of nitrite. Used mainly for aquariums as nitrite, if present in water, can be harmful to fish. The test kit is very easy to use. You just fill up the test tube that is provided, to 5ml. There is a marking on the test tube so you know when it has reached 5ml. You then add 5 drops of the solution provided, put the lid on the tube, then shake it for 5 seconds. Wait for 5 minutes, then compare the colour of the water to the colours on the test card. It is that simple. Depending on the colour, the instructions can give you some advice on what to do, which is very helpful. They go into decent detail to explain some things, the headings are.... 1 - Why test for nitrite? 2 - Testing tips 3 - Directions (step by step guide on how to test water using the kit) 4 - What the test results mean 5 - Reducing aquarium nitrite levels 6 - Reducing pond nitrite levels These are written in English, then translated into French, Spanish, Italian, Portuguese, German, Dutch and Swedish. The test kit includes 1 - Nitrite test solution (with childproof safety cap) 2 - Test tube with lid 3 - Instructions 4 - Nitrite colour card The test can be done up to 180 times with the solution provided. The colour card has six different colours. The ranges are 0 ppm, 0,25 ppm, 0.50 ppm, 1.0 ppm, 2.0 ppm and 5.0 ppm. You can see the colour card in the picture that I added above. It also has a step by step picture guide on how to test your water. I mainly purchased this for when I was cycling my fish tank. Once the ammonia started to go down, the nitrite level was rising. I had to keep an eye on this level so I knew when to do water changes so my fish didn't become too sick. My fish tank successfully cycled, but it is also useful to check water levels after cycling. I normally test for nitrite 2 days after the weekly water change when all levels are settled. I believe that test results can be distorted if you test too soon after a water change because of the reaction in the water when you add dechlorinator. My nitrite has stayed at 0ppm but it puts my mind at rest to know for sure. All in all, this test kit has been very helpful to me, especially during the stages when I was just beginning my fish hobby.

Used it today for the very first time, never used anything like this before and it was spot on. Got more fish after I done the testing. Brilliant and easy to use. I do like it. I still had to take a test of water to the marine shop for them to test other things in the tank water. But I am happy with this test so easy and simple to use. I like the fact it has a little test tube with it.

nitrite api great for testing nitrites when setting up new tank 5 drops. good price dearer in pets at home.

Good and easy to use. I didn’t score the Accuracy because I just assume it’s accurate otherwise a big company like API wouldn’t be selling it.

I really enjoy using the API liquid tests, I find they’re the most accurate and clear to read. However, the glass vials I am not a fan of. Right when I opened the box and set the vial on the table it rolled off and shattered. That’s the second vial that has broken on me. One of the other API kits I have came with a plastic vial with a lid attached and I wish all were like that. They’re easy to rinse out, I would recommend getting some pipettes to measure out the correct amount of water into the vial. Makes it so much easier and less messy. Overall, had it not been for the glass I would have rated five stars.

Great price very essy to use 5 drops of liquid in to the test tube provided Wait 5 mins & you have your results Brilliant best prices anywere

Used for my ponds I found it gave much more accurate results than test strips do. Very easy to use, just one agent and 5 drops per test and you get 180 tests. I don't think you can beat this. Recommended.

Test works perfectly as advertised. Unfortunately it arrived with the contents just loose inside the amazon packaging and the colour card was missing. Fortunately the product page has a picture of the card I can use, otherwise the test would have been completely useless to me.

Produit très simple d'utilisation, fiable et pas cher, le top!

Great product, easy to use with instructions and accurate.

Easy to use. But I have to assume it is giving the correct reading. The colours can be a little vague.

Did not come with the color chart card
